Eto Native Controls
An overview of Eto Native Controls with the minimum code to get started.

Buttons API

Buttons offer simple click → action functionality.

using Eto.Forms;
using Eto.Drawing;
using Rhino.UI;
 
var parent = RhinoEtoApp.MainWindowForDocument(__rhino_doc__);
 
var button = new Button() { Text = "I am a button" };
button.Click += (s, e) => { MessageBox.Show("You clicked me"); };
 
var dialog = new Dialog()
{
  Padding = 8,
  Content = button
};
 
dialog.ShowModal(parent);

Drop Downs store a collection of items and force a user to choose one, drop downs are favourable when the length of data can change or is more than 3-4 items.

using Eto.Forms;
using Eto.Drawing;
using Rhino.UI;
 
var parent = RhinoEtoApp.MainWindowForDocument(__rhino_doc__);
 
string[] items = new [] {
    "Point", "Curve", "Brep",
};
 
var dropDown = new DropDown()
{
    DataStore = items,
    SelectedIndex = 0
};
 
var dialog = new Dialog()
{
    Padding = 8,
    Content = dropDown
};
 
dialog.ShowModal(parent);

Radio Buttons API

Radio Button Lists store a list of items and force a user to choose one item. Radio Buttons are not suitable for longer lists and instead a Drop Down should be preferred.

using Eto.Forms;
using Eto.Drawing;
using Rhino.UI;
 
var parent = RhinoEtoApp.MainWindowForDocument(__rhino_doc__);
 
string[] items = new [] {
    "Earl Grey", "Rooibos", "Oolong",
};
 
 
var buttonList = new RadioButtonList()
{
    DataStore = items,
    Orientation = Orientation.Vertical,
    Spacing = new Size(4, 4)
};
 
var dialog = new Dialog()
{
    Padding = 8,
    Content = buttonList
};
 
dialog.ShowModal(parent);
Eto Combo Box

Check Boxes API

Check Boxes can exist individually or as a group by using the CheckBoxGroup. Check Boxes have 3 states, checked, unchecked and indeterminate. The 3rd state can be set using Null as the Checked value is bool?.

using Eto.Forms;
using Eto.Drawing;
using Rhino.UI;
 
var parent = RhinoEtoApp.MainWindowForDocument(__rhino_doc__);
 
var checkBox = new CheckBox()
{
    Text = "Check Please",
    Checked = true,
};
 
var dialog = new Dialog()
{
    Padding = 8,
    Content = checkBox
};
 
dialog.ShowModal(parent);

Text Box API

The Text box is meant for simple, short inputs like an email address, password, name, etc.

using Eto.Forms;
using Eto.Drawing;
using Rhino.UI;
 
var parent = RhinoEtoApp.MainWindowForDocument(__rhino_doc__);
 
var textBox = new TextBox()
{
    TextAlignment = TextAlignment.Center,
    Width = 200,
    PlaceholderText = "example@email.com"
};
 
var dialog = new Dialog()
{
    Padding = 8,
    Content = textBox
};
 
dialog.ShowModal(parent);
Eto Combo Box

Text Area API

The text area is for longer, multiline text values and offers more options suited to a larger text input.

using Eto.Forms;
using Eto.Drawing;
using Rhino.UI;
 
var parent = RhinoEtoApp.MainWindowForDocument(__rhino_doc__);
 
var textArea = new TextArea()
{
    TextAlignment = TextAlignment.Left,
    AcceptsReturn = true,
    Width = 200,
    Height = 200
};
 
var dialog = new Dialog()
{
    Padding = 8,
    Content = textArea
};
 
dialog.ShowModal(parent);
